‘This is an exceptionally rare piece,’ says specialist Vasiliki Paloympis of the intricate bronze ram-form wine vessel that may be the only one of its kind in the world. Cast in the form of a ram, the piece dates from the 13th-11th century BC.

‘This vessel was made during the Shang Dynasty, and is likely to have been cast in the Yangtze River region,’ continues Paloympis, who describes the object as one of several ‘masterpieces’ to come to Christie’s from the Fujita Museum in Osaka, Japan, whose collection comprises more than 5,000 Japanese and Chinese works of art.

Animal-form vessels are the rarest form of Chinese archaic bronze: ‘Only a handful of comparable pieces are known to exist, although none are rams that are this elaborate, or in such good condition,’ says the specialist. This piece is particularly remarkable for the exceptional detail with which the ram’s features have been rendered — from its carefully ridged horns, to the ‘comma’-shaped nostrils.

‘It’s likely that this vessel was used during ritual offerings to the ancestors to appease the spirits, and thus to gain good fortune,’ says Paloympis. Aspects of this ram, including the diamond-shaped pattern on its forehead, indicate that the craftsmen who made it intended to represent a sacred creature, rather than a real animal. On its back, a mythical kui dragon is typical of Southern bronzes.

‘As a specialist, I’ve handled a lot of Chinese bronze, but this example really stands out,’ Paloympis states. ‘It’s just 22cm [8⅝ in] long, but it has an incredible presence — a buyer isn’t ever likely to find a piece as good as this on the market.’
